Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a document fair copy device which is effective when text is formatted and output with prohibition processing.

[Technical background of the invention and its problems]

To create texts in European languages, copy the texts created on the computer into
It is widely practiced to use a so-called formatter to shape and print in a desired format (for example, printing according to the paper size, performing follow-up printing, right-left alignment, etc.). Functions of such a fair copy program,
The operation or actual configuration method is well known to those skilled in the art, and there are many references, so that it will not be described further here. References include, for example, "Software Manipulation", Chapter 7, Document Formatting, pages 335 to 386 (author: Brian Kernighan, PJPlauger, translator: Izumi Kimura, published by Kyoritsu Shuppansha).

Traditional clean copy programs have been used only to format Western text. However, in recent years, Japanese text processing has come to be emphasized, and it has become desired that the clean copy program operates not only for Western texts but also for texts containing Chinese characters. Furthermore, it is preferable that non-European languages other than Japanese, such as Chinese and Korean, can be printed in the same way. In constructing such a multilingual document fair copy device, a new problem has never occurred so far.

One of such problems is related to prohibition processing. The kinsoku process is, as is well known, to prevent a specific character from starting or ending a line. For example, when "." Is at the beginning of a line, "." Is not at the beginning of the line by erasing one character from the previous line and inserting it in this line.

In a conventional clean copy program for Japanese language processing, character sets that should not come at the beginning of a line and character sets that should not come at the end of a line are fixed and their character codes are embedded in the code of the program. It couldn't be changed by the side. However, if you try to use such a clean copy program not only in Japanese but also in Chinese and Korean, there will be problems with prohibition processing. That is,
Character sets subject to prohibition processing are different between these languages, and even if they are the same character, they may be different in character code. Further, which character is subjected to the prohibition process even in the same language is slightly different depending on the person. Therefore, the document clearing apparatus using the conventional clearing program cannot cope with such a situation.

[Object of the Invention]

It is an object of the present invention to solve the above-mentioned problems of the prior art and to cope with the difference in the prohibition processing between languages and individuals by using a single document fair copy device.

[Outline of Invention]

According to the document fair copy device of one embodiment of the present invention, the user can change the character set to be subjected to the prohibition process in the document fair copy device for performing the prohibition process as necessary. In order to do this, in the present embodiment, such a character set is designated by the parameter of the follow-up processing designation command embedded in the text.

Example of Invention

FIG. 1 shows a functional block diagram of a document copy writing apparatus according to an embodiment of the present invention. In the figure, the text to be printed is read from the input unit 12. In this text, in addition to the body to be printed, commands for controlling the shaping operation of the document printing device are embedded. In the present embodiment, one of such commands is a command for instructing the start of the drive-in process. This command has the following:
A parameter can be added to specify a character set that must not start at the beginning of the line (hereinafter referred to as a non-starting line set) and a character set that cannot start at the end of the line (hereinafter referred to as a line ending prohibition set): .fi p '"((''s'.,.,")]' That is, in the above-mentioned example, it is instructed to perform the follow-up process for the part after this command in the text. In addition to this, each character in the character string enclosed by a pair of apostrophes following p as an end-of-line prohibition set (in the above example, "([is a Each character (.,., ")] In the character string enclosed by is specified.

In FIG. 1, when the input unit 12 detects such a command, the command is sent to the run-in command processing unit 16 and analyzed. The drive-in command processing unit 16 sets the switching unit 22 so that the output of the word generation unit 14 passes through the drive-in processing unit 24. The drive-in processing instruction section 16 further extracts the end-of-line prohibition set and the start-of-line prohibition set from the command and stores them in the first buffer 18 and the second buffer 20, respectively. If one or both of the end-of-line prohibition set and the start-of-line prohibition set is not specified in this command, the contents of the corresponding buffer cannot be rewritten. Therefore, when the chasing process is once canceled and the chasing process is restarted by the .fi command again, the same prohibition process as the previous time is performed unless the above-mentioned parameter is added to this command.

Now, when the input unit 12 takes in something other than a command, that is, a text body, this is sent to the word generation unit 14.
Here, words are cut out one after another from the entered text,
Send to the drive-in processing unit 24. If non-European text, such as Japanese text, is given here, 1 such as Kanji or Kana
Cut out one letter as one word. As a result, the document fair copy device can handle both European and non-European languages in a unified manner. In addition, since the processing of non-European language will be described below, the explanation will be made assuming that the word generation unit 14 outputs one character at a time (note that non-European "characters" are treated as European "words". Needless to say, the drive-in processing unit 24 described below operates without any problem even for a text containing a European language).

The drive-in processing unit 24 receives a character string from the word generating unit 14 and adds this character string after the line currently being assembled one after another. When detecting that the end of this line exceeds the right margin, the drive-in processing unit 24 turns the last added one character to the first character of the next line.

Here, compare each character at the end of the line and the first character of the next line with each character in the end-of-line prohibited set in the first buffer and each character in the prohibited set in the beginning-of-line prohibited set of the second buffer. To do. If the results of these comparisons do not match, then the current row is established in its current state. If either of them matches, the character at the end of the current line is pushed to the next line and becomes the first character. Here, the above-mentioned comparison and, if necessary, eviction to the next line are repeated.

Next, the drive-in processing unit 24 adjusts the position of the character at the end of the confirmed current line so as to completely match the right margin. This may be done by proportional printing, as is well known, or by inserting blanks everywhere in the line.

The drive-in processing unit 24 sends the current line created as described above to another processing unit 26. This line is printed by the output unit 28 after undergoing necessary processing there.

Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made if necessary. For example, a plurality of buffers for storing the end-of-line prohibition set and the start-of-line prohibition set may be provided and switched. Further, the internal operation of the drive-in processing unit 24 may be different from that described above.
Further, the output is not limited to the printer, and may be output to the display, for example. In addition, it is a symbol at the end of a sentence in the European language. It may differ depending on the country whether 2 spaces or 1 space is required after?!. Therefore, which one to select is specified by the parameter of the command instructing the drive process. You can also

〔The invention's effect〕

As described above, according to the present invention, the prohibition character set can be freely set and changed, so that it is possible to provide a document fair copy apparatus that can cope with the difference in prohibition processing depending on the language.
